Former Frazer Township, Pa. officer Michael McSherry pleaded guilty to stalking estranged wife he tracked with department's license-plate reader

Former Frazer Township, Pennsylvania police officer Michael McSherry was arrested September 28, 2021 and later pleaded guilty to stalking and official oppression for a months-long campaign against his estranged wife, Alexandria Griffith, that included logging into his department's license-plate-reader system at least 85 times between August 28 and September 15, 2021 to track her vehicle and her mother's, a hidden GPS tracker discovered under her car, a nanny camera, and repeated threats. On September 10, 2021, responding officers found McSherry holding a loaded handgun during a domestic incident in which he had thrown the couple's four-year-old son to the ground and threatened self-harm before a brief standoff ended in his arrest; a second arrest on September 28, after search warrants turned up additional phones and tracking devices, brought the stalking and computer-misuse charges. A Westmoreland County judge sentenced McSherry to 11.5 to 23 months in jail plus five years of probation, with several felony counts -- including child pornography and terroristic threats -- dismissed as part of the plea agreement.

Michael McSherry, a Frazer Township, Pennsylvania police officer who had previously spent three years with the New Kensington Police Department, began using his department's license-plate-reader (LPR) system in March 2021 to look up the vehicle registration of his estranged wife, Alexandria Griffith. A GPS tracking device was discovered hidden under her car's dashboard at the end of that month. Investigators later determined McSherry logged into the LPR system at least 85 times between August 28 and September 15, 2021 -- while off duty, using his personal phone and computer -- to check on Griffith's and her mother's vehicles; Griffith's own victim-impact statement put the combined total of vehicle-tracking instances across both women's cars at over 250. McSherry's final shift at Frazer Township was September 3, 2021, after roughly six weeks on the job, meaning some of the logged searches continued after his own employment there had ended.

On September 10, 2021, police responded to a domestic incident at a Paulownia Drive residence in Allegheny Township after McSherry, during a confrontation, threw the couple's four-year-old son to the ground. He then barricaded himself with a loaded 9mm handgun and threatened self-harm before a brief standoff ended in his arrest. In the days that followed, McSherry called Griffith 73 times over Facebook Messenger in roughly an hour on September 14 after smashing his own cell phone, and texted her evidence on September 16 that he had accessed her phone account to view messages from as far back as 2013. Search warrants executed September 20 at a hospital and at a Natrona Heights residence recovered multiple phones and a suspected additional tracking device. A second arrest followed on September 28, 2021, bringing formal stalking and computer-misuse charges.

McSherry pleaded guilty on December 15, 2021 in Westmoreland County court to misdemeanor charges of stalking and official oppression. As part of the plea agreement, prosecutors dismissed two felony counts of unlawful computer use, a child pornography count, a harassment count, a second official-oppression count, and a terroristic-threats count. The judge sentenced him to 11.5 to 23 months in jail, with credit for time served since his September 28 arrest, plus five years of probation, and ordered him to have no contact with Griffith, their children, or her family.

Access to a government license-plate surveillance network is authorized for law-enforcement purposes, not personal ones, and an officer's duty to enforce that limit applies equally to himself. A Frazer Township, Pennsylvania police officer used his department's license-plate reader system to track his estranged wife's and her mother's vehicles dozens of times over several weeks, part of a months-long stalking campaign that also included a hidden GPS tracker, a nanny camera, and an armed standoff in which he threw his young son to the ground and threatened suicide before his arrest. This archive records the event as another instance of an officer converting a public-safety surveillance tool into an instrument of personal control over a private citizen, this time compounded by threats and violence against his own family.
